Due to poor lifestyle choices, a certain human's body is in constant turmoil. With germs, bacteria, and foreign substances abound, the jobs of various cells become increasingly difficult and dangerous. As some of the unfortunate ones who matured in this chaotic environment, Sekkekkyuu AA2153 and Hakkekkyuu U-1196 strive to fulfill their duties—even if it means seeing many of their fellow cells lose their lives in duty.

Set in an environment vastly different from its parent story, Hataraku Saibou Black portrays the cells' struggles as they try to maintain the body's health. However, the human's condition continues to deteriorate, and whether or not these efforts will amount to something concrete depends on the cells!

What happens when you put something as wholesome as Cells at Work with addictions and bad habits in a blender? Well, Cells at Work Black is what you get.

Cells at Work Black is an anime that I refused to watch in a beginning. I thought it was going to be a blunder. When I first saw it would come out, I thought that it was going to be the same but with reversed roles. How wrong I was! If some people disliked Cells at Work because of the lack of characters as such, with this one there shouldn’t be many complaints.

The story is Cells at ...

Hell yeah

Do you suffer from depression or do you want to fix your body? Well this is for you. Since you get to realize how much shit is going on in your body

Story: Unlike the original Cells at Work this is depressing. This tackles more depressing things just as alcoholism, excessive smoking, liver failure, heart attack and more. It is just a fun and depressing watch

Characters: Characters are pretty well done. Of course the waifu in this season is the white blood cell. Our main character himself is a hard worker which is respectable since the body is total shit

Music: OSt is good and the ...

I think me watching a show about the human body and all the things that can go wrong with it while in the middle of a global pandemic probably wasn’t the smartest thing but I don’t think it really matters too much. I was looking forward to this series regardless since it essentially was the darker version of Cells at Work and Cells at Work season one was a solid anime back in 2018. But let’s not talk about its parent series and focus on the one right in front of us. A series that doesn’t require you to watch its parent series to jump ...
